Will miners be motivated to step in and power diesel generators to mine Bitcoin, Litecoin, and other Proof-of-Work coins? Seems logical as oil prices will likely drop--or remain suppressed, in coming months

Blockstream exec Samson Mow doesn’t believe that Bitcoin’s proof of work helps support the price. I guess he didn’t learn in Blockstream school that POW is the very thing that gives Bitcoin it’s security and immutability. Without POW it’s just a database.

Want to see Bitcoin price rise? We should create a Proof-of-Work algorithm that changes automatically every year.

Is it possible to have an algorithm that changes slightly every year depending on the most recent merkle root as entropy?
This would kill the ASIC market and would make CPU/GPU mining profitable again.

[Guide] How to make money in EFT

EDIT : Thanks to everybody for pointing out the few mistakes/improvements that can be made in this new-player level guide.
For the sake of summarizing here :
- Intel documents are NOT worth 250k. I didn't check them on the flea before writing this and for some reason I always remembered them at 250k. Game is in maintenance so I can't check the real price. That being said, it's still profitable to craft USB into Intel, it's just not x2 profitable.
- Scav case : moonshine / intel docs, some people seem to say they've never been profitable. I personally *did not* measure those, I eyeballed it. I'm working on so much shit that I didn't bother. On average I think that I'm in a net positive, but it's as believable as people saying they're not : without proof we can't really say for sure. That bein said, it's certainly more profitable to run lower-tier scav runs that are *faster* when you're online, and to run a moonshine or intel when you log off. It's more efficient to get a lot of runs while you can re-start them every time.
- Crafting moonshine : It's not profitable to spam it ; I was under the assumption that the average player who will read this will usually not play for 4-5 hours straight and will end up collecting yesterday's moonshine, craft a new one, and that's it. If that's you're rythm then yes, spam it. If you intend to play more than one craft worth's of time, then you will craft moonshine faster than you can spend it, and it's not really worth to sell it on the flea except to up your market reputation for a small loss (about 10k). So in short : craft moonshine to be able to start a moonshine run for when you log off, but you don't *need* more than that.

Check this out

Here is some actual data on the lavatory !!

Hey everybody !

I know it can be a struggle to get a stable economy in this game, especially when you die a lot. Today I'm gonna try and give a few guidelines on how to make money safely, efficiently, fast, or in any other way we can think of.
If you're struggling to stay above the 15-20 million rouble treshold, this guide is definitely for you.
Very often I'll hear newer players say "Damn I can't seem to make money, I keep loosing. Every time I take gear I die instantly". There is some truth in that. Today I'll help you improve your survival rate, but most importantly I'll unbalance the other side of the equation. When you complain about losing a lot of money, I will help you spend less by a significant margin, as well as earn more. You'll also get rid of gear fera naturally.
Remember this throughout this very, very long read : It all depends on how you want to play, and how much. Some of these tips will not fit how you want to play the game, and like Nikita always says : this game is supposed to be fun before anything else.

1. Hideout

Safety Score : 100%
Reward : Moderate but very stable.
Maxing your hideout should be one of your top priorities, probably before telling your mom how much you love her every now and then. If you're not doing either of those, the big gamer in you knows what to do.
Early wipe, save your fuel for when you're online and playing. If you're playing, your generator should definitely be running and all your stations should be crafting something.
Once you have Medstation 1, Workbench 1 and Lavatory 2, you really have no reason to turn your generator off when you're playing.
Once you have the bitcoin farm, you should never turn off the generator.
Medstation :
Craft salewas and/or IFAKs permanently. They cost 8k and sell for 15k. That's a net profit of about 25k / hour for salewas, as well as never having to buy any.
Lavatory :
Always be crafting Bleach. If you have 2 empty blue fuel, use those empty cans to craft a Magazine case.
You can then keep the magazine cases until you've enough for your liking and sell those for a good profit.
The bleach you will use to buy the 6B47 helmets which are better than the SSh-68 helmets. Buying from 2x bleach barter at ragman level 1 means you get the helmet for 18k (instead of 33k on the market). This helmet has better head coverage, less slow/negative effects, less weight, has a slot for a mount, has +11 ergonomics AND is cheaper than the 22k SSh-68. That being said, it has a slight noise reduction that the Ssh does not have. If you wear headphones I'd say this is negligible but debatable. I prefer to have the extra protection and ergonomics for sure, considering it's slightly cheaper.

You can also barter for that helmet and instantly sell it back for a profit (five times) and level up ragman money requirements.
Bleach can also be traded for the Blackjack backpack at level 4, as well as the TTV rig at level 2. You should definitely do it.
Sell excess bleach on the flea market when the prices are around 10.5k or more. (around midnight Central European Time).
Workbench :
You can buy Power Cords and craft Wires forever and always make a profit. Buy in the morning and sell in the evening for better profits (CET timezone). For even more profit, you can craft gunpowders and ammo which tend to also be ridiculously pricy at night.
Buying grenades from Peacekeeper and crafting green (Eagle) gunpowder is a good way to make a lot of money and level up Peacekeeper.
Intel Center :
You main objective is to get this one to level 3 for reduced fees and better quest rewards, but also access to the bitcoin farm at level 2.
If you need FiR for quests, craft that. When you're done craft Intel Documents at all times (buy the USB), and use it for scav case or sell for a x2 profit. ( 3x40 for USB = 120, documents sell for 250)
Bitcoin Farm :
Once you have it, spend all your money on GPU until its maxxed, then level it up even more. The BTC farm is definitely worth it. At 50GPU you need to connect every 15 hours to clic. If you can't, keep it level 2 and connect every 24 hours to clic. Even at level 1 its worth. But its much, much faster at higher levels.
From 0 to 50 GPUs it takes about 30 days to pay for itself. GPUs should not be sold until you maxxed it.
Water Collector :
Must be running at all times. Buy the components if you don't have them.
Booze Generator :
Must be running at all times. Buy the components if you don't have them.
Scav Case :
Always have it running on moonshine, and use intel documents once you're done crafting one.
Nutrition Unit :
It's not really worth crafting sugar to put in the Booze gen, as the price for chocolate is pretty much = the price of sugar. So buy the sugar instead and craft something else. I tend to craft Hot Rods when the prices are good (morning) and then use them to barter 5.45 BS Ammo with Prapor or sell for a profit.

If you do all that, you should have about 150k an hour fairly easily. Don't forget to check it between every raid.

2. Traders

Safety Score : 100%
Reward : Quite good.
Once your mom has received all the love she deserves and your hideout is taken care of, you should have max traders (traders are a requirement for most of the hideout anyway).
Traders level 4 will net you much better prices on most mods and open very good barter trades.
Buy as much as you can from barter trades. You can buy almost everything from it, and it's usually at least 25% cheaper to buy the requirements and then do the barter. Ragman4 has the CPC Armored Rig which is level 5 armor, you'll get it for about 200k instead of 250k on the flea. The Slick is also much cheaper. The Blackjack backpack is literally half priced.
You can also NOT use what you barter and just sell it back to a dealer (sometimes the same from which you bartered) for a profit as well as having 2 times the loyalty money increase (from bartering then from selling).
Another good example is buying a Recbat 14k from the market, getting an ADAR for skier, selling it to Mechanic and winning 8k just like that. You can find every single barter that nets a profit yourself and just buy-resell and you'll probably make another 100k every reset, if you really are struggling and have the patience. I personally advise to just use the equipment for yourself unless you're levelling traders, but I wouldn't go as far as buying all profitable items every reset.
Every trader at every level has good barters. You can make a full decent kit at level 1 traders for about 40k roubles on barter, instead of 90 if you buy it all. (Paca for masks, helmet for bleach, ADAR for recbatt, salewa from craft, backpack, etc. all barters)

Bleach is beautiful and is coveted in the real world for its ability to cure diseases.

3. Modding

Safety Score : 100%
Reward : Very profitable.
Don't mod out of your reach. Don't mod Meta. If money is an issue for you, having +1 ergo won't change your life.
For example,
Priced at 10k roubles
Priced at 45k Roubles

See where I'm going with this?
If you have money, sure, go for the Shift. If you wanna have fun and try, sure, go for it as well. But if you're struggling, buy 4 cobras and mod 4 guns for the price of 1% recoil which will not make you a gamer god anyway.
Also, do NOT buy mods from the flea market when you see you can buy them from traders. Look at the top of the market, if the mod is greyed out, look at the price. It means you don't have access (yet). If the price is too inflated for you, find another mod. There are always other mods. You can make 2 AKMs that have a difference of 2% recoil and 4 Ergonomics and have a 150k price difference. It's up to you. When money is the issue, this was the answer.

Note : Some guns are inherently much more expensive. Guns shooting 5.56 or 5.45 tend to be more expensive than 7.62. AKMs are VERY good budget guns. They're a bit harder to handle, but you can get a fully modded AK for 150-200k, where as you will have an entry level M4 for that price. 7.62 PS ammo is also incredibly cheap while being decent. Play 7.62 if you're struggling with money. It's not meta, but it's far more than enough, trust me. You'll rarely lose fights exclusively because you had PS ammo in an AKM. Rarely.

4. Statistical loadout balance

This is fairly simple yet overlooked a LOT. To be accurate, you need data. Personally I kept it in an excel spreadsheet, if you're hardcore you should do something similar.

A somewhat relevant spreadsheet I used a wipe ago to measure some of my stats
What you need to know about yourself for this :
These will help us measure how much you fuck up or not.
Lets make it simple.
If you have a 500k loadout and you usually extract with 100k, at 10% survival rate, that means you will spend 500k x 10 = 5.000.000 roubles over 10 raids on average, die 9 times, and earn 100k once. This very obvious example shows the loss.
Basically we're gonna try and balance that equation so that you never lose money on average. You'll have ups and downs obviously, but over a week or two, it'll smooth things out for you, like math always does in a pleasant conversation with a girl.

So what can you do to improve that equation ?

4.1 Improve survival rate

Seems simple enough, DIE LESS. You do not need to be good, smart, or special to die less. If you die a lot, do something different. If you die less, try more of that. Explore statistical advantages through different gameplay.
What can you do to die less practically? Here is a list of checkboxes you can tick depending on your money, skill, mood, or any other factor like the map and sheer luck:
Do all that, it'll give you a LOT of data to actually improve by just doing something different without really being fastestronger, just smarter.
And I repeat : you can do some of it, all of it, it depends on what you like, what you're comfortable with, and the time/investment you're putting in the game. It's okay to play at your own pace.

4.2 Reduce gear cost

The second part of our "profit equation" above is how much gear you take with you. Using previous tips, reduce that cost. Barters, cheaper mods, etc.

4.3 Increase extracted value

This one is not as tricky as it sounds. Basically there are two ways to extract with more money in the backpack :
The goal is to pay for the gear you will loose when you die while making a profit on top. That one time you extract if you have a MBSS backpack, you'll need items worth like 50k per slot to break even. If you take a tri-zip, suddenly it's only 30k per slot. If you take a blackjack and blackrock from good old ragman, suddenly it's 10k per slot. So you can break even by looting crickents and DVD players almost.
See where I'm going ? Always take a tri-zip or bigger unless you're doing something special. That way you can afford to loot shitty areas, take less risk, and survive more while having a little less value.
We'll cover that in a minute, but there are ways to loot high value items, moderate value and low value. Those have also different risk/reward.

All of those are also map specific. In woods I'll often go with a 6B3TM armored rig for 40k, no helmet, 20k headphones and a sniper rifle. Rest is pouched so does not count. That's less than 100k investment. All players tend to have low value gear so I never extract with a lot either so it balances out. But on Woods, my survival rate is 20% instead of my overall 40%. So I know it's not a map I can reliably make money on, because I measured that accurately over time. This example is very common and should make sense to you.
Same goes for interchange where I have more about 50% survival but will tend to go in with 600k worth of gear, but will also often extract with over 500k quite regularly. Different ratios, different values, different purposes.
You can measure your own data if you're willing to do so, or you can eyeball it. Eyeballing it is much faster but very inaccurate because you will tend to include emotions in the mix when you die. You'll remember losses ~2x more than your wins (that's somewhat scientifically proven), and if you're eyeballing your loadout you might think you have 600k but really you might have only 450k. I would advise to go hardcore and measure it all for price, initial loadout, losses and earnings, for each map.

5. Money runs

Now money runs are vast and numerous. All include different levels of risk and reward. It's up to you once again to find what you're willing to do for the time it takes, the fun it will give you and how much it will actually help you. You can always try them all for ~50 raids the sake of trying something different and see how your data is impacted. it doesn't have to be 50 in a row if you don't want to. As long as you keep track of it it can be over a whole wipe. You'd have your data ready for the next wipe :) Faster is better though.

5.1 Hatchling runs

Safety Score : 100%
Reward : Very Variable. Mentally exhausting.
Those are incredibly money efficient. You're investing a gear of 0 value, so whatever you extract with is 100% win, so you cannot possibly lose money that way. Is it fun? Is it rewarding? I don't care, to each is own. Statistcally speaking, hatchling runs are an efficient way to make money.
They do however require a little bit of knowledge, but not skill. You'll be much more efficient at doing these kind of runs if you know where to go, what to look for, and how to get there depending on your spawn. That being said, such knoweldge is easily found ; it's nothing complex, it just takes time to learn. Once again, depends on how much you're willing to invest (if not roubles, time).

5.2 Scav runs

Safety Score : 100%
Reward : Low-ish
Scav runs are also incredibly efficient for the same reason as hatchlings. Except those have a cooldown. Statisticall speaking I have noticed you should always run your scavs as fast as possible on the map where you extract both the fastest and most frequently.
The explanation is simple, lets make it simpler :
The scav is a button that makes you earn free money. When you press it the button becomes unpressable for some time, when you release the button you earn money (sometimes).
That means you want to release the button as often as possible. And for that, you need to release it as fast as possible. It's that simple. So make scavs incredibly fast. I'm talking "Run through" fast.
Unless you're looking for FiR items or doing something specific like annoying a streamer, you should literally run straight to the extract every single time, and loot what you have that doesn't make you go out of your way too much. Usually I suggest factory, go in, kill a random scav, loot it, get out.
Two weapons is at LEAST 50k, 100 if they have a scope. There you go. That's 100k every 20 minutes (or less with intel center). That's MUCH BETTER than going up to 150-200k but taking 30 minutes to extract, and taking more risk by spending more time in the map. Every second you're in someone can shoot. Nobody can shoot you in the hideout.
The exception to that rule is Scavs with a pilgrim which you can take on your favourite loot-run map, probably interchange or reserve. There you should just fill everything you can and extract once you're full, no matter what you have. 30 crickents and an extra gun is fine.

5.3 Stash runs

Safety Score : Very
Reward : Okay
Those are very very safe and can be done with a pistol and a backpack only. Very cheap, quite unchalleneged, for a moderate reward. Just go on a map that you like and run around and loot all stashes until you're full, then get out. You can vary the map/route depending on the traffic of players. Interchange and shoreline are good contenders for that.
It'll net you easy money. Not great money, but definitely safe.

5.4 Loot Runs

Safety Score : Moderate
Reward : Quite alright
Once you have better knowledge/skill you can start having a specific route in a specific map, depending on a specific spawn. So it'll take time to learn. Usually very similar than a hatchling run except this time you bring moderate gear and go for moderate loots. For example, instead of going for fast techlight, in-and-out interchange, you can decide "alright I'll loot 100% of Oli and the computers in the back", it'll take time, but it'll make good loot. More money than stashes, definitely will see scavs to kill, and most probably some more pvp. More risk. If you win that PvP you have even more loot as well. But overall good reward.
Loot runs need to be "scheduled" and thought of after several tries, so you know how much you can take per person depending on backpack size. For example you can't say "lets loot oli" if you have a 5-man with blackjacks, you'll all be empty. Adapt.

5.4 PvP

Safety Score : Insane
Reward : Unreliably moderate
This one is pretty obvious. Very risky, unpredictable rewards. Usually better than loot runs when you survive. I won't elaborate on this, because if you're reading this far you're probably struggling in PvP. And the rest of this guide already covers a fair bit.

6. Insurance

Safety Score : "Meh"
Reward : Very profitable.
Now this is very, very important. Always insure your gear. Always.
If you die you will get stuff back, pretty much for free. If you're really struggling people won't loot your "trash", so you WILL get it back.
If you play in a group it's very likely that people will hide your stuff too.
And most importantly : you can insurance fraud. This is the best way to balance the equation we talked about earlier. If you find a decent-ish gun, replace yours. You drop your initial investment by a significant margin, you will definitely get it back, and if you extract it's a flat profit. Weapons don't take inventory slot, so if you have two weapons that are not yours initially they will usually pay for your whole gear. I have quite often left my super-mega-modded HK just for an average M4 or other weapon that I can fight with, just so I can reduce my investment by 350k and up my reward by like 200k instantly. Replace your headphones all the time too, that's an easy -30+30k, same with helmets. even if it's a bit broken or slightly worse.
If you're struggling with money, try to leave every raid with at least 3-4 pars of your equipment that aren't yours initially.
But value the risk behind this. I won't leave my slick for a Paca at the third minute of a raid just to have that extra 28k. I won't leave my meta-modded HK for a naked mosin. But if it seems decent/doable, do it. It will pay off. Because even if you die, you still get your shit back, and gun is usually the most expensive part of the gear.

7. Final notes

It's all about balance. Find what works *for you* and try shit out. Really, try. You'll die, you'll learn, you'll adapt with data to back that up. I find it crazy that people will die and not try to learn from it. That's how you will improve as a player.
First you gotta get smarter, then you'll get better. And with time, skill, mechanics, gamesense, all that will improve on the side. Earning more will snowball in your favour. And if you know you're statistically okay, you will have a much smaller gear fear and enjoy the game more.

Sorry for the wall of text, you guys should be used to it with me by now :D I made these guides in video but not in english, so here I am typing it all for you guys.
Enjoy :)

Can we just talk about how crazy the network hashrate is currently ?

We regularly go above 150Ehashs/s now....
I think too many people don't realise that proof of work applied to transaction confirmation/decentralized timestamping is a such powerful idea, even after the halving the hashrate still increases to reach levels never touched before thanks to technical progress in specialized hardware in which miners throw energy they won't use otherwise.
The bitcoin token is the best money to buy this hashrate through transaction fees so that you can write what you want in the Bitcoin ledger that is the most legit document the humanity ever created thanks to proof of work (just by reading the blockchain content, you know it is legit document). The price of Bitcoin and the transaction fee market reflect how much people need a legit and unforgeable ledger to settle their contracts.
Altcoiner's fud of death spiral because of halving was a complete lack of understanding. Nothing can replace what proof of work and Bitcoin are doing: incentivize the creation of specialized hardware to create the most legit ledger ever made of history.

[WTS] Auction Leftovers #2 (Older/Better World Silver ONLY)

Good morning again!
Okay - so Round 1 of "Leftovers" worked out pretty well...found a lot of new homes for coins from my collection. As a result, I'm going to give it a second shot with leftovers from the September 13 Auction.
NOTE: I'm also going to incorporate some lessons learned from last time that will hopefully streamline the process.
This listing is for items that did not sell during the September 13 Auction (most likely due to BP/fees) - so you can buy anything you want right here and right now - no buyer's premiums, no additional fees - JUST DISCOUNTS:
*All the World Silver is 10% off the listed price.
*FREE shipping for any order over $100.
*NUCLEAR OPTION: Buy everything that remains for 15% off listed asking price.
Each lot was individually imaged (front and back) for the auction - so the easiest way for you to see exactly what you're buying is to visit the auction link (the auction is over, so I'm not advertising anything different or advertising an upcoming auction) - so here that is:
https://www.auctionzip.com/auction-catalog/Coins-US,-Foreign-,-Rare,-Graded,-Type,-Jewelry,-More-2_PD4EXTCK7K/
Here is the required "prove you still have the stuff" photo with the username card and today's date (I pulled the first five items out of the storage trays so you weren't just seeing the tops of bags):
PHOTO
Payment: PayPal. I do not have Venmo/Zello/Bitcoin or any other form of digital payment at this time. No notes if using PPFF, please. Thank you.
Shipping: I will charge you what it costs me for the USPS label rounded up to the nearest dollar. For First Class that is usually $4, for USPS Priority Mail Flat Rate Small Box it will be $9. I will get you a tracking number right after payment is received and will get your package scanned into the USPS system within 24 hours of receipt of payment. I will offer "Risky Shipping" (via stamped greeting card) at my discretion for $1 - for single, small coins ONLY.
What do YOU need to do to buy coins from this group: send me a list of which lots you want (for example, I want to buy lots # 51, 52, 53, 54, 55) and I will send you a total. There are too many coins here (plus there are duplicates) so I cannot look up the coins you want by description - just give me lot numbers and it will be much simpler.
I'd like to make a simple and polite request - if I have sent you my PayPal information (meaning we've agreed to a deal) please finish it up as soon as you can so I can check you off the list and move on to the next person. This helps make sure you get all the coins we discussed and no one else is in limbo.
I will do my absolute best to update the ad as soon as lots sell.

Reasons why NANO fails and will keep failing until some things change

Dear NANO community,
This is going to be a long post where I will discuss why NANO under performed and will keep under performing in this bull run unless some things change.
I'm going to start up with straight facts with the famous quote of Floyd Mayweather: "Men lie, women lie, numbers don't lie".
If you feel offended by some of this, facts don't care about your feelings.
Technical Analysis
In the time where BTC Dominance fell from peak of 74% to 56% and keeps falling, NANO has moved from its low of 0.0000640 sats to a price of 0.0000950 sats. That is about 50% gain if you bought on the absolute low, but looking at the monthly chart, we can see that NANO has basically been in the range of 0.0001400 sats to 0.0000750 sats ever since July of 2019 (for more than 2 years).
https://charts.cointrader.pro/snapshot/zaXzV
The all time high of NANO was 0.0028, so this price is currently 96% down in terms of BTC .
https://charts.cointrader.pro/snapshot/tTF4J
With this price NANO is falling out of top 100 cryptocurrency based on market cap.

My thoughts: Considering that entire altcoin market is moving and that it keeps reaching new highs, this is very concerning for NANO and one can only ask themselves why does NANO keep falling behind?
Why does on every Bitcoin pump price falls hardest and on every day when other altcoins go up 30%, NANO only goes up 10%.
Reasons why NANO is lagging on the market:
We all know that NANO has near instantaneous transactions and is fee-less which is why most of us fell in love with this cryptocurrency.
Problem is that it has little to no adoption. What does it matter if NANO is feeless, when you don't have an exchange that will make a NANO/USD conversion for 0%.
Who cares if STR, XRP and other fast coins have like 0.01$ fee if either way, exchange will take 1% or more fees from you.?
If XRP has better exchange, they can easily be more cost efficient than NANO because of this problem. Devs need to be much more proactive rather than sit and wait while entire market is eating you alive.
Proposed solution: Nano needs to invest more in marketing and in making a deal with exchange that will be liquid enough and provide little to no fees on NANO.

I am a NANO holder ever since 2018 and it's been a long ride with constant buying at the end of each month with average buy of 2$ when I look at it totally.
This is not that bad considering NANO's massive fall and what some other holders had to go through.
Let's remind ourselves again, NANO has 0% inflation. And yet NANO's price doesn't grow. Where as other cryptocurrencies have 5-10% inflation and they are over-performing NANO massively.
NANO holders get no rewards from holding NANO which is a big problem. People call this an advantage and I somewhat agree, but NANO holders need to be rewarded with something, because crypto space doesn't care about inflation.
Proposed solution: Introduce POS (Proof of Stake) with inflation of 5% where NANO holders will be able to stake their NANO and receive 5% more NANO each year. You can do this or make it 6% and after each 2 years, there is halving of inflation. Imagine how coins get hyped when their rewards per year get cut in half. NANO has 0% inflation and it doesn't get any hype. It's already scarce, but people fail to see it.

Current bull run has been ignited with DEFI and because people see that they can earn up to 3-5% daily income just for holding ERC20 token like BAT, BAL, LINK etc. There's even been introudect WBTC (Wrapped Bitcoin) and WETH (Wrapped Ethereum), which means that people can hold their cryptocurrency which they would hold even if there weren't any rewards and they get 3-5% daily income + the chance of the DEFI coin actually pumping by 1000+% which many of them have done in the past month.
Because of all of this people are massively buying ERC20 tokens just to get these gains daily.
What has NANO do to interact with this entire DEFI space? Absolutely nothing.
Did they try to introduce wNANO (wrapped NANO) like Ethereum and Bitcoin did? No.
They just kept working on some other bullshit even-though protocol is in of itself 99% perfect and working. They keep focusing their energy on technology when technology is already better than anything else on the crypto market. NANO is currently the best fast cryptocurrency and it is not even close.
Proposed solution: Devs need to start focusing energy on things that matter and which will help the price and not dump their stash and blindly look how everything else keeps growing.

This is similar to reason number 2 but it has to be said separately. Just ask yourself, who benefits of BTC markets? Miners.
Who benefits of any other POS market? All of the holders.
And then with this money you can finance devs which will work on the currency and will by this raise the price and the whole cycle repeats itself.
So all of these things have in common that people are making money of doing something for the ecosystem. On one hand resources get paid, on the other people that are loyal to the project.
NANO has one of the best and largest communities in cryptocurrency and numbers confirm this, yet there is no special way for any of us to benefit of of this. Everything is open source and people make everything for free.
Proposed solution: Introduce mechanism so that community members can earn money of holding NANO.

Conclusion: Nano is an amazing currency, but there are many things that need to fall in place in order for it to stop falling behind the market.
It's sad that investing in what is called a "safest" altcoin Ethereum, would've made you much better gains than even buying NANO on the all time low would.
This post is meant to be constructive criticism and to in the end open peoples mind on current problem NANO has in the space.
Please share this post so more people and hopefully devs can see it and so that we all as a community can start working towards our goal of NANO becoming one of most utilized cryptocurrencies in the world.

Feather - free, open-source Monero desktop wallet releasing soon™

For the past year tobtoht and I have been working on the foundations of a new Monero desktop GUI called Feather for Mac OS and Linux platforms (Windows tentative) using Qt5, libwallet, QtWidgets.
The goal of this new wallet is to provide a practical, robust and easy-to-use Monero wallet for every day use. It aims to be beginner friendly, but should also cater to the needs of experienced Monero users with the addition of advanced features like coin control and multisig.
Feather's user interface is inspired by Bitcoin's Electrum wallet, but adapted to fit Monero. Feather is not a fork of Electrum, all of the UI code was written from scratch in C++ / QtWidgets.
Development began in the summer of 2019. We estimate to release a beta version in November or December.

Video preview

Why

Our primary motivation is to create a wallet that we ourselves would want to use and recommend to friends. There aren't many options when it comes to non-custodial Monero desktop wallets. The CLI is an excellent tool for power-users, but is simply not an option for users that are not familiar with with the terminal. The GUI has a slick user interface, but is demanding on system resources due the use of Qt Quick.
Instead we've taken inspiration from Bitcoin's Electrum and started working on the most basic looking Monero desktop wallet one can imagine. We've gotten rid of a lot of functionality, but also added new functionality. Just focussing on the basics results in a clean, robust, and beginner proof wallet.

In an effort to mitigate unintentional off-chain linking, we have made it harder to reuse addresses by automatically hiding used subaddresses. We find that the primary address leads uninformed users to believe that it is somehow functionally incompatible with subaddresses, or that funds sent to subaddresses can not be spent together. To encourage the use of subaddresses the primary address is hidden by default, and only used for change and coinbase outputs.
Our wallet supports advanced coin control features like freeze/thaw and sweeping a single output. In the future we may add manual transaction input selection.
There is no need to manually setup Tor to protect your traffic, Feather comes bundled with Tor. By default all traffic is routed through Tor with the exception of traffic between wallet and daemon. Wallet synchronization over Tor takes substantially longer than over clearnet, but you can optionally enable to connect to remote nodes over Tor. If your machine already has a Tor daemon running Feather can use the system daemon when instructed.
Just like in the official GUI, Feather essentially has 2 modes of connecting to the Monero network. You either host your node somewhere (localhost/LAN/internet) or we'll provide you one from a list of trusted, stable, community hosted remote nodes (like Cake Wallet). If Feather detects that it's running on Tails or Whonix it will automatically connect to a random .onion remote node.

Performance

Feather is built with Qt Widgets, providing native looks and performance. In a recent test™ a wallet with 10k+ transactions only consumed 200 MB ram (before optimizations). In comparison, the official GUI uses 400 MB before a wallet is opened.
GPU power is plenty nowadays so this hardly a problem, however, we are serious about providing an user interface that feels snappy to use. The application itself starts within 1-2 seconds on most machines (Bitcoin's Electrum is more like 4-5 seconds due to their usage of PyQt).

User experience

We have implemented Tevador's 14 word seed scheme with embedded restore height. The same function is used to derive the private view key from the private spendkey, therefore it is possible to convert the 14 word seed into a standard 25 word seed in case you want to restore the wallet using the official wallet software.
Feather connects to a websocket server over Tor to obtain miscellaneous data such as: price information, a list CCS proposals, posts on /Monero, the most recent blockheight, a list of community hosted nodes and the latest version of Feather.
The websocket server itself is open-source and self-hostable. By default Feather will connect to a server hosted by the project maintainers. The websocket connection can be disabled completely, but some functionality will be disabled/broken.
Our target audience are users who want to use Monero without too many issues and we've designed the wallet as such, with lots of convenience features, while routing it all over Tor in the background.
The native look of the application should feel familair to users as it behaves like any other program that runs on their computer. Added benefit for future contributors/developers is that it's very fast to implement/test UI components by borrowing from QtWidget's vast library. This in contrast with the Monero GUI, which uses custom QML components - a tricky and time consuming rendereframework more suited for large teams to create electron-like applications.

Additional information

Proposal

Work started early summer 2019. We still have some features to finish, prepare CI/CD, etc. As such we expect an alpha or beta release in December 2020. For this we would like the community's approval to allow the milestones defined in GUI CCS to be used for the remainder of this project, paid in full - we can use the support. Consequently all code will be licensed under the Monero Project and features/changes to libwallet or wallet2 will be committed to upstream (Monero GUI/core). Future development and releases will be maintained by dsc__ and tobtoht.

Beta testing

Idle in #feather on irc.oftc.net if you want to help beta testing in a month or so. You will need Linux, as this is our primary platform for developing the application.
Please let us know what you think in the comments. We're open to suggestions/feature requests/brainfarts.

Why you have to hire a hacker in 2020

Hiring a hacker could reveal security flaws in your organisation. The global cost of cybercrime could reach £4.9 trillion annually by 2021, according to a recent report from Cybersecurity Ventures. Cyber crime incidents continue to plague organisations globally, even as businesses pour money into boosting their security. But how do businesses deal with vulnerabilities they cannot identify? It only takes one smart hacker to discover a backdoor and get access to your sensitive data and systems. Organisations must identify the weaknesses in their cyber security, before -- not after -- they’re exploited by hackers. However, to beat a hacker you’ll need to think like one. Here’s how -- and why -- you should hire a hacker in 2020.
The stakes have never been so high
State sponsored hacking wreaked havoc in 2016 when Yahoo revealed that 1billion accounts were compromised in the largest data breach in history. And as cyber crime becomes increasingly advanced, the threat hackers pose to businesses will only increase. Leave your organisation open to a data breach and it could cost you a massive £4.25m (on average). And that’s without considering the painful remediation and brand damage you’ll be subject to as a result. These attacks aren’t restricted to huge multinationals, the latest Government Security Breaches Survey found that 74% of small organisations reported a security breach in the past year.
For any organisation, a security flaw passing undetected is a huge risk, and when GDPR hits in 2018 the stakes will only increase.
The EU General Data Protection Regulation will come into force in 2018 and will govern how businesses handle customer data. Compliance won’t be easy, and the risk of non-compliance is massive, with potential £17million fines. Big businesses aren’t safe from this, and they’ll need to boost their data security to ensure compliance. Tesco were recently lucky to escape a £1.9bn fine for a recent data breach. How hackers will boost your cyber security Not every hacker wants to attack your business and leak your sensitive data. There are hackers out there who are paid to protect, not provoke. Known as ‘white hat’ or ‘ethical hackers’, these security professionals strive to defend organisations from cyber criminals. They’re not your conventional dark web lurking delinquents. Ethical hackers are IT security experts -- trained in hacking techniques and tools -- hired to identify security vulnerabilities in computer systems and networks. According to ITJobsWatch, the average salary for an ethical hacker is £62,500. Considering the average cost of a data breach sits at £4.23m, that’s a small price to pay. Businesses and government organisations serious about IT security hire ethical hackers to probe and secure their networks, applications, and computer systems. But, unlike malicious ‘black hat’ hackers, ethical hackers will document your vulnerabilities and provide you with the knowledge you need to fix them. Organisations hire ethical hackers to conduct penetration tests - safe attacks on your computer systems designed to detect vulnerabilities. To test their security, businesses often set goals or win states for penetration tests. This could include manipulating a customer record on your database, or getting access to an admin account –potentially disastrous situations if they were achieved by malicious hackers. Ethical hackers leverage the same techniques and tools used by hackers. They might con employees over email, scan your network for vulnerabilities or barrage your servers with a crippling DDoS attack.
But instead of exploiting your business, ethical hackers will document security flaws and you’ll get actionable insight into how they can be fixed. It’s your responsibility to act on the ethical hacker’s guidance - this is where the hard work begins. Without these harmless penetration tests security holes remain unseen, leaving your organisation in a position that a malicious hacker could exploit. Not your typical dark web delinquents Thankfully, the days of hiring underground hackers and bartering with bitcoins are over. There’s now a rich pool of qualified security professionals to choose from, complete with formal ethical hacking certifications. Ethical hackers, or penetration testers, can be hired just like any other professional, but be certain to get tangible proof of your ethical hacker’s skills. Ethical hackers, or penetration testers, can be hired just like any other professional, but be certain to get tangible proof of your ethical hacker’s skills. Candidates with the CEH certification have proved they know how to use a wide range of hacking techniques and tools. What’s more, CEH certified professionals must submit to a criminal background check. These experts are committed to their profession and do not use their hacking knowledge maliciously. Despite the relative youth of the ethical hacking field, these professionals have already proved their worth to some of the largest businesses in the world. This year Facebook awarded a white hat hacker £32000 -- its largest ever bounty -- for reporting one ‘remote code execution flaw’ in their servers. That’s not the first time Facebook have paid out either. They’ve long supported the efficacy of bug bounties, having paid more than £4 million to ethical hackers since it’s program debuted in 2011.
How to hire a hacker (legally)
It’s important to understand what you actually want from your ethical hacker. Do this by creating a clear statement of expectations, provided by the organisation or an external auditor. Ethical hackers shouldn’t be hired to provide a broad overview of your policies, these professionals are specialised experts with a deep knowledge of IT security. Instead, ask specific questions like “Do we need to review our web app security?” or “Do our systems require an external penetration test?” Before hiring an ethical hacker to conduct a penetration test, businesses should ensure an inventory of systems, people and information is on-hand. Instead of hiring, many organisations develop ethical hacking skills in their own businesses by up-skilling team members through ethical hacking courses, like EC-Council’s CEH or the more advanced ECSA.
Advertisement Your staff will get the skills they need to conduct ethical hacking activities on your own businesses, finding and fixing security flaws that only a hacker could find.
Secure your business now
Complex threats -- like rapid IoT expansion -- are set to dominate 2020. To defend your organisation in 2020, you’ll need to think like a hacker.

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
https://github.com/dragonchain/spirit-bomb

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

A theory of why Ethereum is perhaps better "sound money" than Bitcoin.

The idea of Bitcoin's supremacy as "sound money" is very frequently thrown around by the biggest talking heads in the crypto world. I know I will get a lot of hate for suggesting that this theory is not only flawed, but it is straight up wrong. As unintuitive as it may sound to Bitcoin maximalists (no offense intended) I believe Ethereum is on the path to becoming the global leading asset and model for sound money... give me a chance to explain why.

  1. The idea that nothing can change Bitcoin's issuance schedule is a myth. There is absolutely no divine power controlling the supply of Bitcoin. Contrary to what is commonly asserted, Bitcoin's issuance protocol is not primarily driven by what is currently implemented. The real driver is consensus: the majority of network participants must agree that what is currently defined cannot be changed. There is an underlying assumption that the consensus would never want to change Bitcoin's issuance. On the surface this makes for a nice "sound money" narrative, but it is false premise and sticking to it could be ultimately detrimental. It presents a long term sustainability issue (the hope that somehow Bitcoin's base layer will scale enough to maintain security entirely through fees). It also completely dismisses the possibility that an unforeseen event could create pressure to change the issuance. If Bitcoin managed to create a consensus mechanism that did not rely on mining, it is very likely there would be consensus to reduce issuance. On the other hand, if some potentially catastrophic event would create incentives to increase the issuance, it would only make sense for the network to do so.
  2. Issuance flexibility is not fundamentally bad. Etheruem's approach to adjust the issuance according to the contextual circumstances has resulted in a faster rate of issuance reduction than what was originally defined in the protocol. The rate of issuance will continue to decrease as new developments allow for it to happen without compromising the network security. There is a very high probability that Ethereum will achieve a lower issuance rate than Bitcoin in the next two years, and it could possibly achieve zero issuance in the next five years. This would be a result of a successful implementation of PoS, sharding and EIP-1559.
  3. The root of all evil is Proof of Work. PoW is by far the primary cost of operating the Bitcoin network. It is the primary determinant of how much issuance is needed as a financial incentive to keep miners doing their thing. The very mechanism that secures the network's decentralization is unfortunately quite wasteful. The degree of decentralization is a direct result of how much random mathematical operations are being done by miners.
  4. There is a better way. Some people will take offense by the use of the word wasteful, and they claim that it is not because those mindless calculations are what is actually securing the network. However, its wasteful aspect becomes clear if there is a different way to achieve equal or superior decentralization without the need to crunch difficult computational problems. This just so happens to be embodied in Ethereum's design of Proof of Stake. It will drastically reduce the cost of securing the network, while providing at least 2-3% annual returns for the ownership of Ether. When Ethereum's issuance becomes lower than its staking rewards, it will effectively have achieved the same effect as having zero (or possibly negative) issuance.
  5. The value proposition of Ethereum 2.0 is unmatched. There is just absolutely no asset in the world that has a 2-3% self-denominated annual returns and just so happens to be rapidly appreciating. When wall-street's greed sees this, it will create the mother of all bubbles.
  6. Don't dismiss the flippening. On February 01 2018 Ethereum reached 70% of Bitcoin's marked cap (it was even closer if you account for the amount of lost bitcoins). That happened before DEFI, before proof of staking was within reach, before multiple effective layer 2 solutions were a thing, before wrapped Bitcoins and before the first signs of mass adoption were on the horizon (like integration with Reddit , VISA and potential to compete with SWIFT). Utility is a huge factor in driving prices, lets not forget how Silk Road played a key role into propelling Bitcoin's value. Yes, Ethereum crashed hard after the peak in 2018, but perhaps it is simply manifesting a higher volatility pattern that is reminiscent of Bitcoin's early years. Bitcoin's first 5 years were characterized by aggressive price swings, why should it be different for Etheruem (considering it is about 5 years younger than Bitcoin)? If the volatility patterns stands on this bull market, we will see a flippening.
So... do I think Etheruem will flip? Yes I do, but I still hold Bitcoin. No one has a crystal ball, and nothing is certain. Perhaps Etheruem will crash and burn, perhaps Bitcoin will become the next Yahoo, and perhaps they will both thrive in this new exciting crypto world.

Proof of work, thus, isn’t the only barrier to such attacks. There are others. Alas, this shouldn’t discount the fact that PoW is costing just 0.5% of the transaction volume over the Bitcoin network, a very low fraction. PoW Meaning. Proof-of-Work (PoW) was the first successful decentralized blockchain consensus algorithm. PoW is used in Bitcoin, Ethereum (Ethereum plans to switch to Proof-of-Stake), Litecoin, ZCash, Monero, and many other blockchains.. The most famous algorithm works as follows: at the beginning, network users send digital tokens to each other, then all transactions made are collected in ... This paper is where the term Proof of Work (PoW) was coined. Now, fast forward to 2008. That year, Satoshi Nakamoto published the Bitcoin whitepaper, “Bitcoin: A Peer-to-Peer Electronic Cash System.” Here, Nakamoto explained, What is Bitcoin? He also put forth a method for applying Proof of Work (PoW) to cryptocurrency. If the price of bitcoin mining does move lower as a result of a change to optical proof of work, the bitcoin price could move below the $3,000 it dropped to 12 months ago before miners were forced ... Bitcoin uses a consensus mechanism called “proof of work” (PoW) as a method for miners (nodes) to verify the information and form new blocks on a blockchain, in order to earn new bitcoin. This so-called “miner’s reward” gets reduced to half after every 210,000 blocks mined, which takes place roughly every four years.
